Dipak said: (Dec 4, 2010) | |

Which formula to use? |

Prabu said: (Dec 6, 2010) | |

Why you take *100? |

Devi said: (Dec 14, 2010) | |

S I = P*R*T /100 P = (100 x S.I)/(R x T) |

Rsd said: (Jan 28, 2011) | |

too simple |

Munjal said: (May 5, 2011) | |

What is P.C.P.A.? |

Jyothi said: (Jun 1, 2011) | |

P.C.P.A. stands for Percent Compounded Per Annum. |

Machender said: (Aug 28, 2011) | |

@Jyothi absolutely right. |

Atharva said: (Feb 5, 2012) | |

I=P*N*R/100 4016.25=P*5*9 4016.25=P*45 P=4016.25/45 P=89.25*100 P=8925 |

Bhaskar said: (Aug 8, 2012) | |

Why 9 is in denominator, The formula is P.R.T/100 and here the Rate and Time is in numerator ? |

Mani said: (Aug 25, 2012) | |

Refer important formulas in S.I @ bhaskar |

Muali said: (Aug 20, 2013) | |

S.I = P*R*T /100. |

Mudassir Pasha said: (Sep 17, 2013) | |

We can solve this problem logically also without using SI formula. Here the the total interest amt given for 5 years is 4016.25. Therefore for the total interest for 1 year is 4016.25/5 = 803.25. Therefore 803.25 is the 9% of the total sum. If we calculate the 100% of the 803.25 we will get the the total amt. To calculate 100%, multiple 803.25 by 100 and divide it by 9. 803.25*100/9 = 8925. |

Kruba Karan said: (Sep 4, 2014) | |

What is another way to solve this problem? |

Fortune said: (Sep 29, 2014) | |

Hey I am not able to divide 401625/45 it is easy with calculate but manually I'm not able please help me and make it easy for me step by step. |

Vipin Mishra said: (Oct 4, 2014) | |

First take a LCM of 401625 Then you can calculation easily. |

Bhavna said: (Dec 10, 2014) | |

@Fortune. We know that P = S.I*100/R*T. Given S.I = 4016.25, R = 9, T = 5. Substitute these values in above formula, Then, P = 4016.25*100/9*5. P = 4016.25*20/9 (Cancel 100 with 5). P = 80325/9. By simplifying this we get. P = Rs.8925. Hope it is understandable. |

Chinna said: (Jan 17, 2015) | |

It is very simple. Just multiply rate of interest and time. i.e, 9x5 = 45%. Here 45% = 4016.25 then. 100% = ? Hence 100% = 401625/45 = 8925. Thank you. |

Thies said: (Apr 13, 2015) | |

What about the interest on interest? |

Lahari said: (Apr 19, 2015) | |

How to represent the time? For eg: If 2 years and 8 months like that given. |

Mohd Dil said: (May 30, 2015) | |

Please tell me detail. |

Shridhar said: (Jul 24, 2015) | |

2/3 years. For 12 months 1 year. For 8 months? 8/12. |

Karthika said: (Jul 31, 2015) | |

I can not understand this problem. |

Swapna said: (Aug 31, 2015) | |

Simple interest = P*T*R/100, P = 100*S.I/T*R, = 100*4016.25/5*9 = 8925. Principal means sum here. |

Ganesh said: (Apr 1, 2016) | |

Then what is the difference between P. C. P. A and P. A since we use the same formula so we get the same answer? |

Swapnil said: (Jun 1, 2016) | |

It is very easy. Take 9 * 5 = 45. 45% = 4016.25. 100%= ? By cross multiplication we get the answer is 8925. |

Manju said: (Jun 26, 2016) | |

If you go through the important formulas you will definitely find formulas to find each value differently. Here sum relates to the principle so the formula for principle is P=100 * SI / R * N. SUBSTITUTE the values in it, you will get the solution, that's it. |

Muthumani said: (Jul 4, 2016) | |

P=100 * SI / R * N. Where, P - amount. R - rate. I - interest. N - year. |

Karibasappa said: (Nov 11, 2016) | |

How easily divides the long fractions? Please help me. |

Kenchappa said: (Nov 11, 2016) | |

Please, anybody tell me, How to divide this one 401625/45? |

Joyal said: (Dec 14, 2016) | |

Can't the interest added by the previous interest? |

Kalian Jee said: (May 2, 2017) | |

Simple interest = 4016.25. Rate = 9%. Time=5 year's. Sum = si * 100/r. Sum=4016.25 * 100/9 * 5, = 401625 ÷ 45. Sum = 8925 answer. |

Thiru said: (Jun 9, 2017) | |

Here, S.i = p * n * r/100. Ans = 401625= P * 5 * 9/100 Next step 401625 * 100/5 * 9 = p then 40162500/45 => Ans = 8925. |

Lakshmi said: (Jul 27, 2017) | |

I understand your concept thanks @Bhavna. |

Shreekant said: (Sep 11, 2017) | |

Why 100 is multiplied? |

Neelesh said: (Nov 2, 2017) | |

HERE IS AN INTERESTING TRICK: Since, the rate is 9% for 5 years, so total SI is 45%. Now 45% = 4016.25 so 100% = 4016.25*100/45 = 8925. |

Parkash Jha said: (Nov 4, 2017) | |

5 years = 4016.25. So, 1 years = 803.25. Now formula, Rate % = Interest/principalx100(only for 1 years). So, principal=803.25/9x100=8925. Hence principal = 8925 ans=(C). |

Vinaya said: (Jan 14, 2018) | |

Hi friends! I am Vinaya. Here we have to find d sum(p). So formula we know is S.I=P*R*T/100;. SO, p=S.I*100/R*T--->given S.I=4016.25 we can write it as 401625/100...R=9,T=5. Substitute the values ...P=401625*100/100*9*5.. After calculation, we get 8925. |

Shahi Fazal said: (Jan 17, 2018) | |

Total S.I-Rs4016.25. Rate-9% Time-5yrs S.I.=[P*R*T/100] So, P=[S.I.*100/R*T] P=[4016.25*100/9*5] =8925 Ans. |

Faustina Paradise said: (Jan 31, 2018) | |

We can also use the formula. Simple interest =principal *rate *time all over 100. 4016.25=p*9*5/100, 4016.25=45p/100, Then cross multiply; 45p=401625, divid both side by 45. p=8925. There the sum = 8925. |

Vineeth said: (Jun 17, 2018) | |

A=p(1+RT/100). A=total money, borrow, P=lended,loan,sum, R=rate, T=time. |

Kalyan said: (Aug 8, 2018) | |

Simple interest = 4016.25. Rate = 9%. Time=5 year's. Sum = si * 100/r. Sum=4016.25 * 100/9 * 5, = 401625 ÷ 45. Sum = 8925 answer. |

Arun said: (Aug 13, 2018) | |

Here, p.c.p.a Indicates the rate for compound interest. |

Nimazz said: (Nov 8, 2018) | |

How 401625/45? Please explain in detail. |

Anomie said: (Mar 15, 2019) | |

P.C.P.A. Stands for Percent "Compounded" Per Annum. Then why simple interest is given in the question? |

Mit said: (May 12, 2019) | |

Is it asking for principal or principal+ interest. Please tell me. |

Basil said: (Jun 13, 2019) | |

P.C.P.A is percent compound per annum. Why is it using simple interest formula? |

Karthick said: (Sep 25, 2019) | |

Why we take 100? I can't understand this problem. Please anyone explain this problem. |
